Abstract:
An optical disc drive apparatus includes: a first optical pickup and a second optical pickup which record data on an optical disc and reproduce data recorded on the optical disc; a slide mechanism which has the first and second optical pickups mounted thereon to slide the first and second optical pickups in a radial direction of the optical disc; a seek command receiver which receives a seek command; a first optical pickup controller which causes the first optical pickup to perform a search on the basis of the seek command received by the seek command receiver; a slide mechanism controller which controls the slide mechanism on the basis of the seek command received by the seek command receiver; and a second optical pickup controller which turns off a tracking servo of the second optical pickup when the first and second optical pickups are slid by the slide mechanism.
